1 Claim. (Cl. 15-164) This invention relates to improvements in portableglass cleaning devices adapted for use in a container for holding waterand a detergent.

The principal object of the invention is to provide a glass cleaningdevice of the stated character which is simple in construction, strongand effective, and easy to assemble and clean. A device of this kindlends itself to a high degree of sanitation and the arrangement andconstruction of its parts are such that all parts are easily cleanedwith a minimum amount of effort.

Another object of the invention is to provide a glass cleaning deviceincluding spaced banks of brush holders arranged on supports and whichare easily removable for cleaning and replacement in alternatepositions.

The invention resides further in certain structural details hereinafterset forth and illustrated in the attached drawings, in which:

Figure 1 is a top plan view of my invention, partially in cross section.

Figure 2 is a side elevation in cross-section of my invention takenalong the line 2-2 of Figure 1.

Figure 3 is a fragmentary view of my device as shown in Figure 2.

With reference to the drawings, the cleaning device, in a preferredform, comprises a holding frame having a hub 11 with a centrally locatedlongitudinally extending aperture 12. Spaced equally about and extendingfrom the outer circumferential surface 13 of said hub 11 are spokemembers 14, two of which are anchored at one of their ends in said hub,and another, as designated by the numeral 16, pivotally mounted within arecess cut in said hub and rotatable on a pin 17 extending through saidrecess and a portion of said hub.

The free end of each of said spoke members is apertured and receivescolumns 18 extending upwardly a substantial distance at right angles tosaid spoke and downwardly a short distance from said spoke members.These latter column extensions 18a have a vacuum cup 19 attached theretoin each instance and in operation engage the bottom surface of a tankwhich may hold water and a detergent.

The upwardly extending portions of the column have spaced recesses 20cut therein, the purpose of which will be hereinafter explained.

Removably mounted within aperture 12 and extending upwardly therefrom isa shaft 21 which is substantially equidistant from all the columns.

A tuft cleaning brush 22 is secured to the free end of said shaft 21 bymeans of a locking pin 15, with a second brush 23 slidably mounted onthe shaft immediately below said brush 22. The brushes 22 and 23 arecomprised of individually bunched fibers 27 secured within cylinders 25with bunches of said fibers spaced equally about and extending outwardlyfrom the outer circumferential surface of said cylinders.

Slidably mounted on said shaft 21 and between the brush 23 and the hub11 is an additional brush 23a,

similar to brush 23, separated one from the other by" collar 26, alsoSlidably mounted on shaft 21. An elongated collar 26a is disposedbetween the hub 11 and brush 23a and is also slidable on shaft 21. Thetufts 27 extendoutwardly from and are spaced substantially equally aboutthe circumferential surface of each tuft holder 27:: and

, are substantially equal in thickness and length.

A number of enlarged removable rings 28 are disposed in the spacedrecesses 20 and arranged in spaced relation from adjacent the top of thecolunms 18 down to and adjacent the top of the elongated collar 26a.Arranged about and spaced equally and extending downwardly at an anglefrom the inside surface of each ring are long tufts 30, the ends 30a ofwhich in assembled relationship extend below and beyond the free ends ofthe tufts 27 and below and beyond the tufts of brush 22.

Attention is directed to the fact that each individual bunch of tufts 30is arranged whereby a portion of one end of each tuft is very closelyconfined within a ferrule 31 which in turn is closely fitted in anopening 32, a series of which are formed within the rings 28.

An enclosing ring 33 of rubber, or other material having similarcharacteristics, is arranged about the free ends of the columns 18. Thisring 33 is made with three spaced notches 34 which are employed tosubstantially encase the free ends 35 of the column 18 and initiallyfunctions as a lock to hold the rings 28 securely in spaced relationshipand in the recesses 20. The inside diameter of the ring 33 is less thanthe combined radius from the center of shaft 21 to the columns 18 sothat to set over the columns 18, the ring 33 must be stretched. Thetension thereby created in stretching ring 33 is used to apply tensionto the columns 18 when the ring 33 tends to expand to its normal shapeand size.

When it is desirable to disassemble the unit, the following steps arefollowed: The enclosing ring 33 is first removed and spoke 16 is swungdownwardly about its pivot point 17. The rings 28 may be readily removedfrom the recesses 20 and drawn upwardly over the brush 22.

- After this is done, the shaft 21, with the brushes and the collars maybe withdrawn bodily from the hub 11. As all of the brushes and collarsare individually mounted, all or a few may be detached independentlyfrom the shaft 21, and it is apparent that such parts can be readilycleaned or easily replaced.

The operation of cleaning glasses in the unit of the present applicationis easy to carry out. The glass 36 is upended, as shown in Figure 3, toforce the open end down over the tufts between the rings 28 and thebrush holders. The upwardly extending tufts of the brush 22 are used toclean the inside bottom of the glass while the tufts 27 clean the insidesurface of the glass, and the tufts 30, the outside surface of theglass. A mere up and down movement of the glass in the unit provides aneffective way to clean the glasses.

Changes in details may be made without departing from the spirit orscope of my invention, but which I claim is new is:

A glass cleaning device comprising a base member having a centrallydisposed shaft mounted therein with said shaft extending upwardly atright angles to said base, a plurality of spoke members spaced equallyfrom said base, a plurality of upstanding columns spaced equally fromsaid shaft but remote therefrom adjacent the outer periphcry of saidspokes and fixed in said spokes, one of said spokes pivoted in saidbase, extensions to said columns extending below said spokes and havingsurface contacting elements mounted on the free ends of said extensions,a series of demountable spaced cylinders arranged on said shaft, spacedtufts of fiber arranged equally about and from the outer circumferentialsurface of each cylinder, said tufts forming a circularly shaped brush,spaced recesses formed in said columns, with like spaced recessesPatented Aug. 25, 1959 a.
